2ft Round LED Trailer Side Marker Lights - Waterproof, Plug+Play

In this review of the NEW SUN 2' round LED trailer lights, the bottom line is clear: these are a practical, low-cost choice for drivers who need bright, compliant side markers that are easy to install. The reviewer found the single biggest reason to buy is the combination of a reflective polycarbonate lens and high-powered LEDs that improve nighttime visibility while meeting D.O.T. requirements. For anyone fitting fenders, trailers, trucks or campers who wants screw-less installation, these lights deliver straightforward value.

Key Features

• Ultra reflective lens: The polycarbonate lens is designed to reflect direct beams for improved visibility at night and adds passive safety when lights are not powered.
• Dual-function design: High-powered LEDs serve as both active side markers and passive reflectors, helping meet D.O.T. FMVSS-108 requirements for larger vehicles.
• IP67 waterproofing: The lights are rated submersible for short periods, making them suitable for wet road conditions and occasional water exposure.
• Easy installation: Each lamp includes a rubber grommet and a standard two-prong plug for quick, screw-less mounting and simple wiring.
• Durable components: Built with premium parts from Taiwan and reverse polarity protection, the lamps are intended for reliable, long-term use on trailers and utility vehicles.

Who It's For

These 2' round LED side markers are well suited for trailer owners, camper and RV users, and small truck fleets that need compliant, visible marker lights with minimal installation time. The plug+play setup and grommet fit make them attractive for DIY installs or quick replacements when maintaining multiple trailers.

They are less appropriate for someone who needs guaranteed boat trailer compatibility in every case, since some users reported issues when specifically used on boat trailers, and for customers who require multi-color or multi-function assemblies beyond basic side marker and reflector duties.

Pros & Cons
